A method for controlling the temperature of a waste heat recovery system and a method for controlling such a waste heat recovery system

摘要

The present invention is a method for controlling the temperature in a waste heat recovery system (4) associated with a combustion engine (2), wherein the waste heat recovery system (4) comprises a working fluid circuit (20); At least one evaporator (22); An inflator 24; At least one evaporator (22) is arranged to pump the working fluid (WF) through the condenser (26) and the working fluid circuit (20) And the condenser 26 of the waste heat recovery system 4 is connected to a cooling system 6 connected to a waste heat recovery system (not shown) associated with the combustion engine 2 4) a method for controlling the temperature inside the apparatus. The method includes: determining (S101) whether the combustion engine (2) associated with the waste heat recovery system (4) is to stop; And controlling the temperature in the waste heat recovery system 4 based on whether the combustion engine 2 is about to stop or not (s102). The present invention also relates to a vehicle system 4, a vehicle 1 including such a system 4, a computer program P and a computer program product.
